The GMC Jimmy utilizes a disc brake system on all four wheels. This system includes brake rotors, brake pads, calipers, and a master cylinder. The system relies on friction between the brake pads and rotors to slow the vehicle down, generating heat in the process.

The most common type of brake system, disc brakes offer efficient heat dissipation and consistent stopping power.
These are the metal discs that the brake pads clamp down on to create friction.
These are the friction material that is pressed against the rotors.
These house the brake pistons and apply pressure to the brake pads, clamping them against the rotors.
This component converts pedal force into hydraulic pressure, which is then sent to the calipers.
The Jimmy also has a separate parking brake system, typically using cables to engage rear wheel brakes.
This fluid transmits the hydraulic pressure from the master cylinder to the calipers.
Some Jimmy models may be equipped with ABS, which helps prevent wheel lockup during hard braking.
If the brake pads are worn down, they will not be able to grip the rotors effectively, leading to reduced braking performance.
Excessive heat can warp or damage the rotors, causing vibrations or pulsating during braking.
Leaks in the brake lines or calipers can lead to a spongy brake pedal and reduced braking effectiveness.
Air in the brake lines can also cause a spongy brake pedal.
